Sam’s making a presentation for his class at Deep Space High – all about the exciting developments in spaceports on his home planet of Earth. He explores what they are and why we need to think about them.

Sam, Stats and Quark take a trip to see one of the busiest satellites in the sky – the Solar Dynamics Observatory. Taking readings across a wide variety of wavelengths, it helps get the full picture of activity around the sun.

Outside the protective magnetosphere, there’s nothing between humans and the powerful radiation from the solar winds. Sam, Stats and Quark find out how it isn’t just astronauts who are at risk – even aircraft passengers can be affected.
